Abstract: A method providing for the selective hydroproces sing of cracked naphtha feedstock to make a low-sulfur gasoline blending component. The method includes the use of two catalytic distillation stages in combination with two stripping columns and two fixed-bed reactors integrated in a novel arrangement so as to provide for the treatment of cracked naphtha feedstock that has a high sulfur concentration to yield exceptionally low-sulfur light cracked naphtha and heavy cracked naphtha products. The desulfurized light and heavy cracked naphtha are produced with a minimal amount of hydrogenation of the olefin content and at may suitably be used as gasoline blending components.

Abstract: Process for preparing a diesel fuel composition comprising the steps of: (i) blending a Fischer-Tropsch derived gasoil with a petroleum derived gasoil to form a blended gasoil which is compliant with the EN590 specification, wherein the Fischer-Tropsch derived gasoil has a density of 0.8 g/cm3 or less and wherein the petroleum derived gasoil is derived from naphthenic high density petroleum crude oil and has a density at 15° C. of 0.84 g/cm3 or greater and a naphthenics content of 30 wt % or greater; and (ii) mixing the blended gasoil produced in step (i) with a diesel base fuel to form a diesel fuel composition, wherein the diesel fuel composition has a density at 15° C. in the range from 0.820 g/cm3 to 0.845 g/cm3.
